Abstract: <P>PROBLEM TO BE SOLVED: To provide a sensor and a sensor manufacturing method capable of simplifying a manufacturing work by facilitating a connection work between a metal terminal member and a connection terminal member without enlarging the volume of a sensor itself.  <P>SOLUTION: A whole area air-fuel ratio sensor 2 has a constitution equipped with a lead frame 10 having a rear end part 20 formed in a shape having a gradually-reduced width size toward the rear end side.
